Book excerpt: Excerpt from Transactions of the American Philosophical Society, 1898, Vol. 19: Held at Philadelphia, for Promoting Useful Knowledge Storangen der kleinen Planeten, undoubtedly marks a great advance in the determina tion of the general perturbations of the heavenly bodies. The value of the work is greatly enhanced by an application of the method to a numerical example in which are given the perturbations of Egeria produced by the action of Jupiter, Mars, and Saturn. And yet, notwithstanding the many exceptional features of the work commending it to attention, astronomers seem to have been de terred by the refined analysis and laborious computations from anything like a general use of the method; and they still adhere to the method of special perturbations devel oped by lagrange. Hansen himself seems to have felt the force of the objections to his method, since in a posthumous memoir published in 1875, entitled Ueber die Sto'rangen der grossen Planeten, insbesondere des Jupiters, his former positive views relative to the convergence of series, and the proper angles to be used in the argu ments, are greatly modified.
